SPRING- COUPLING,

To all whom it may concern:

Be it known-that I, EUGEN STEINHART, a subject of the German Emperor,residing at 81 Schlosstrasse, Dusseldorf, Germany, have invented certainnew and useful Improvements in Spring-Couplings; and I do hereby declarethe following to be a full,

- clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same. 4

' The present invention relates to couplings between front and rear orthe trail and limber portions of vehicles.

Accordingto-the invention the pole ofthecarriage is held in balancewhile free tov move.

easily and so is easily operated, the heavy] blows that occur whentraveling or when inclining the mile or the vehicle are only braked orreduced slightly, namely corresponding to the pull. In order to removethis last disadvantage the limber hook has been constructed as a bellcrank lever, which swings around a horizontalpin-on the draw bar and isspring urged against a support.

Strong springs are necessary for this purpose the compression of whichcauses difiiculties, especially as these springs are as a rule in themost inaccessible places. When a spring hasto be changed owing to abreakage great difficulties are experienced.

The present invention avoids these difiiculties by arranging the springin a sleeve, against which one end of the spring bears,

while the other end of the spring is supported by an adjustable tensionregulating cap. f

In the accompanying drawing the coupling is shown in longitudinalsection, a being the limber eye with which the conically shaped andeasily movable limber hook I) Specification of Letters Batent.

engages. This hook I) is pivoted by a bolt 6 in the extension 0 ofthefixed limber hook bearing d. The lower part of the limber hook I)is-constructed as a spring casing, one end of the spring f bearingagainst a buffer 9 capable of longitudinal movement relatively to thecasing while the other end of the spring bears against the end of thecap or sleeve-like member h which is screwed in the casing. l

By this construction of coupling it is possible to remove thecomparatively great downward pressure of the coupling while a as thecoupling rises the spring is inactive.

I claim as my invention: 1. A coupling for vehicles of the trail andlimber type comprising'a coupling member having a casing, a support towhich said member is pivotally connected, a springpressed bufi'er in oneend of said casing designed to bear against said support, and a cap forclosing the other end of said casing.

A coupling for vehicles of the trail and limber type comprising acoupling member having a casing, a support to which said member ispivotally connected, a buffer fitted in one end of said casing andhaving a limited movement therein, a spring for forcing the outer end ofsaid buffer in "position for engagement with said support, and a cap inthe other end of said casing for regulating the tension of said spring.

3. A coupling for vehicles of the trail and limber type comprising acoupling member having a casing, a support to which said member ispivotally connected, a tubular buffer in one end of said casing, ahollow screw cap for closing the opposite end of said casing, and acoiled spring between said buiier and said cap 'for forcing the formeroutwardly in positionfor engagement with said support.

In testimony whereof,.I haves'igned this specification in the presenceof two subscribing- Witnesses.
